Hey.
I’m still fresh at Zbrush. But the best way to improve is with challenges and contests.
So I accept anyone that wants to challenge me.
Know that I’m not good and there won’t e any price lol.
It’s just for other people that feels the same as me. To improve our skills.
We both will choose the theme.
I think that the time should be for 2 days or something like that.
Nothing too EPIC lol 
Voting will be with polls?
Open for other ideas.
